This copper brake pipe is made of pure copper, by giant Chinese copper tube manufacturers that are ISO 9001 certified.
- Much more flexible than steel tubing
- Extremely easy to bend and flare
- Meets SAE and BS EN standards
- Suitable for ISO/DIN bubble flare, ISO/SAE double flare (inverted flare), and single flare.
Properties
OD | 7.94+/-0.08mm |
Wall | 0.7+/-0.08mm |
Tensile Strength | 40 ksi (205MPa) |
Expansion | 40% min |
Theoretical Burst Pressure | 6365 psi i.e. 43.9 MPa min |
NOTE:
- We can also supply tubing of 0.75mm, or even thicker wall , to further increase pressure resistance.
- Burst pressure calculation could vary according to the stress limit applied to the formula.
Pb=2σbδ/(D0-0.8δ)
Where
Pb– Burst pressure, MPa
σb– Tensile strength, MPa (205MPa applied)
D0– Outside diameter, mm
δ – Wall thickness, mm
